I'm returning to the community after a long time
Now I have some free time, I would like to come back
and hopefully learn enough to hack together a project.
My project would simply be a propeller masquerading
as a desktop computer (obviously its just a look-a-like
and cant do what a PC does).
I would like to have the screen display at 640x480
and be able to address individual pixels on the display.
I appreciate that there is not enough RAM on the P8X32A to do this
So I have a few questions, and I hope someone can point
me in the right direction, a code sample would be even better.
So I want to ask the community which is the best external RAM to use?
I would like to keep the pin count low (in case I need to use 2 or 4) so I expect to use an 8-pin ic.
but which one works best or has an object in the OBEX which I could use to guide me?
I have read the SRAM application note AN012 interfacing propeller external sram
and I think I understand that bit, so I'm hoping to take away something from that and apply
it to whatever ram ic is the best/fastest ram ic recommended by the community.
Also, could I use the same source-code that is in the AN012 and apply it to 23LC1024 with little or no changes?
Finally could someone point me to a vanilla 640x480 vga scan-line driver,
which (I assume) takes the text from the Screen[WidthxHeight] BYTE array
and dumps it to the vga out connector (without specifying a color i.e monochrome ONLY)
If this is wrong forum to post my question in,
then I'm sorry, and maybe a moderator can move it to the right one.
